Abstract
The invention discloses a clamping device for a universal testing machine. The clamping device for the universal testing machine comprises a fixing seat, a pressing plate and a clamp seat. The fixing seat, the pressing plate and the clamp seat are sequentially and fixedly connected, the upper end and the lower end of the pressing plate are provided with fixing screws in a penetrating mode, and the fixing seat and the pressing plate are fixed through the fixing screws. The clamp seat is placed in the middle of the pressing plate, and a base plate is clamped between the clamp seat and the fixing seat. A side-arc-shaped jaw, a linear jaw and a positive-arc-shaped jaw which are arrayed in an arc shape are formed in the clamp seat. The side-arc-shaped jaw, the linear jaw and the positive-arc-shaped jaw are respectively provided with a fixing bolt, and the side-arc-shaped jaw, the linear jaw and the positive-arc-shaped jaw are fixedly connected with the clamp seat through the fixing bolts. The clamping device for the universal testing machine is easy to operate and reasonable in structure, the jaws can be simply and quickly replaced, the work efficiency can be improved, the anti-friction performance of the side faces of the jaws is good, and the clamping effect is good.
Description
Technical field
The present invention relates to a kind of universal testing machine clamping device.
Background technology
The jaw that existing universal hydraulic testing machine is equipped with, in practical work process, constant replacing jaw, very loaded down with trivial details, consumption power, and inefficiency, the wearing quality of jaw side is poor, in use, because pulling force is larger, screw extraction, backing plate is drawn out, and may cause and cannot use.
Summary of the invention
Technical matters for above-mentioned existence, the object of the invention is: proposed a kind of simple to operate, rational in infrastructure, replacing jaw that not only can be simple and direct, increase work efficiency, and the wear-resisting type of its jaw side is better, the good universal testing machine clamping device of effect of clamping.
Technical solution of the present invention is achieved in that a kind of universal testing machine clamping device, comprise holder, pressing plate and clamping fixture seat, described holder, pressing plate and clamping fixture seat are fixedly connected sequentially, the two ends up and down of described pressing plate are penetrated with fixed screw, described holder and pressing plate are fixed by fixed screw, described clamping fixture seat is positioned at the medium position of pressing plate, between described clamping fixture seat and pressing plate, clamping has backing plate, described clamping fixture seat is provided with the side camber jaw of curved arrangement, yi word pattern jaw and positive camber jaw, described side camber jaw, yi word pattern jaw and positive camber jaw are provided with set bolt, described side camber jaw, yi word pattern jaw and positive camber jaw are fixed by set bolt and clamping fixture seat.
As preferably, described holder, pressing plate and clamping fixture seat are all provided with two and for being symmetrical arranged.
As preferably, described backing plate is thermal treatment backing plate.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Universal testing machine clamping device of the present invention, owing to being provided with holder, pressing plate and clamping fixture seat, can for when clamping jaw side wearing quality poor carry out specific aim setting, corresponding backing plate is arranged between clamping fixture seat and pressing plate, with this, improve the wearing quality of jaw side, simultaneously, the side camber jaw of the curved arrangement arranging on clamping fixture seat, yi word pattern jaw and positive camber jaw, can meet existing most of demand, in use, without frequent replacing, the use of only corresponding jaw need being pulled out or retracted.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1 is the planimetric map of clamping device for a kind of universal testing machine of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Consult shown in Fig. 1, a kind of universal testing machine clamping device, comprise holder 1, pressing plate 2 and clamping fixture seat 3, described holder 1, pressing plate 2 and clamping fixture seat 3 are fixedly connected sequentially, the two ends up and down of described pressing plate 2 are penetrated with fixed screw 4, described holder 1 is fixed by fixed screw 4 with pressing plate 2, described clamping fixture seat 3 is positioned at the medium position of pressing plate 2, between described clamping fixture seat 3 and pressing plate 2, clamping has backing plate 5, with pressing plate 2, backing plate 5 is fixed between holder 1 and clamping fixture seat 3, backing plate 5 is difficult for being drawn out, and in use, can two contact planes be refined by backing plate 5, reduce error and friction, described clamping fixture seat 3 is provided with the side camber jaw 6 of curved arrangement, yi word pattern jaw 7 and positive camber jaw 8, described side camber jaw 6, yi word pattern jaw 7 and positive camber jaw 8 are provided with set bolt 9, described side camber jaw 6, yi word pattern jaw 7 and positive camber jaw 8 are fixing with clamping fixture seat 3 by set bolt 9, clamping fixture seat 3 is connected with corresponding motor (not shown) or hydropress (not shown), rotate corresponding switch, and select corresponding jaw, motor or hydropress will stretch out the tight sample of pincers jaw and carry out tension test, closing switch after off-test, then gear makes zero jaw number shelves, test specimens after stretching can be taken out from jaw.
Described holder 1, pressing plate 2 and clamping fixture seat 3 are all provided with two and for being symmetrical arranged, and are convenient to clamp operation.
Described backing plate 5 is thermal treatment backing plate, makes hardness reach drawing requirement, increases wearing quality.
The invention has the beneficial effects as follows: owing to being provided with holder, pressing plate and clamping fixture seat, can for when clamping jaw side wearing quality poor carry out specific aim setting, corresponding backing plate is arranged between clamping fixture seat and pressing plate, with this, improve the wearing quality of jaw side, simultaneously, the side camber jaw of the curved arrangement arranging on clamping fixture seat, yi word pattern jaw and positive camber jaw, can meet existing most of demand, in use, without frequent replacing, the use of only corresponding jaw need being pulled out or retracted.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
